I'm sure we all know this one, which I call RightNow.xaml:

<!-- RightNow.xaml by Charles Petzold -->
<Label xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
       xmlns:s="clr-namespace:System;assembly=mscorlib"
       HorizontalAlignment="Center"
       VerticalAlignment="Center"
       FontFamily="Times New Roman"
       FontSize="24pt"
       Content="{x:Static s:DateTime.Now}" />

It snags and displays the current date and time. The display isn't dynamically updated, alas, but maybe someday, all properties will be dependency properties.
